> Consider the snippet:
> {code}
> interface Base {}
> interface Derived extends Base {}
> interface I {
>   Base[] foo()
> }
> interface I2 extends I {
>   Derived[] foo()
> }
> class C implements I2 {
>   Derived[] foo() { null }
> }
> {code}
> Compilation fails with:
> {noformat}
> The return type of Derived[] foo() in C is incompatible with Base[] in I
> {noformat}
